"High performance hybrid" - an oxymoron? Not according to BMW, which has two new hybrids coming to the upcoming Frankfurt Motor Show. One of the two, the X6 Hybrid, promises to be the most powerful hybrid vehicle ever offered with 478 horsepower and 575 lb-ft of torque from its twin electric motors and 4.4-liter V8 engine combined.

According to what appear to be leaked specs from BMW, the X6 Hybrid will scoot to 60 in about 5.5 seconds while returning a 20-percent fuel mileage improvement over the standard X6 with its twin-turbo V8. To set the hybrid apart from its standard sibling, BMW will bestow the new fuel-saver with a power dome hood (musclecar elements on a hybrid - HA!) and a bespoke metallic blue hue.

Faster yet will be the upcoming 7 Series Hybrid, which will reportedly be able to cover the run to 60 in under five seconds flat via the 459 horsepower and 561 lb-ft of torque provided by its V8-based hybrid powertrain combination. BMW predicts an X6 Hybrid-matching 20-percent increase in fuel efficiency from its 7 Series Hybrid.
